Bollywood actor Dhanush, son-in-law of superstar Rajinikanth, says he is anxiously on the look out for a right script in Bollywood. He has picked unconventional roles to venture into Hindi films, debuting as an obsessive lover in `Raanjhanaa` and a dumb and mute person in his second Bollywood outing `Shamitabh`. Receiving the National Film Award for his co-production `Kaaka Muttai` in Delhi recently, the actor said he would like to do more Hindi cinema. `Kaaka Muttai` is a Tamil drama that narrates the tale of two children and their journey to get their first bite of pizza. The movie won the award in the Best Children`s Film category. His wife Aishwarya has directed him in her directorial debut and the actor`s fans wish to see them work again. But, Aishwarya feels that it is not important that her father Rajnikanth or she direct Dhanush. Dhanush did a cameo in the recently released southern movie `Vai Raja Vai`. The film features Gautham Karthik and Priya Anand in lead roles.
